Assessment of risk for obstructive sleep apnea by using STOP-BANG questionnaire in type 2 diabetes mellitus

Obstructive sleep apnea (OSA) is a disorder of breathing during sleep. It typically presents as repetitive short episodes of partial or complete stoppage of breathing due to upper airway obstruction during sleep and awakens the person. The association between OSA, type 2 diabetes mellitus (T2DM), and obesity has been suggested in numerous studies. It is expected that the prevalence of OSA will increase with rising number of T2DM. Unfortunately, many of the patients are not aware about OSA and also remain undiagnosed. The questionnaire-based OSA screening for risk stratification is validated in many studies in diverse populations. This approach can help early detection of OSA in T2DM. Hence, the study was undertaken to find out prevalence of OSA in T2DM patients by validated screening questionnaire, STOP-BANG. Objective of the study is to assess the prevalence of OSA among the type 2 diabetic patients attending tertiary care hospital.
This was a questionnaire-based cross-sectional study done in a tertiary care hospital affiliated to a medical college in Maharashtra. The number of respondents were 374 attending diabetic clinic, who were interviewed using STOP-BANG questionnaire and assessed on four symptoms and four signs to stratify the OSA risk.
47.3% of type 2 diabetics had STOP-BANG score ≥ 3, which is high-risk score for OSA
Type 2 diabetics are at risk of OSA and STOP-BANG questionnaire could detect nearly 50%. The screening is simple and can be used in primary care setting. These sub-set of patients can be subjected to gold standard polysomnography at home or in hospital for further management.
